i would like to know how much power you can get without slipping a stock auto tranny in a second gen. it has 155k on it and its been stock its whole life.
thanks

 

I put a #6 fuel plate pushed all the way forward, a cold air intake, strait pipe and my tranny started to slip. At that point I had 145k miles on mine. It only slipped when I pushed the fuel plate forward though. If you get a heavy duty tourque converter and a heavy duty valve body, and at least a pyrometer, then you can get a lot further with performance upgrades. It might be ok if you get a #6 fuel plate and not adjust it as far as I did. Hope this helps!

 

ya thanks alot i just wanted someone with some experience with theres so i didnt have to experiement on my friends

 

Sounds like you have a nice truck from your sig. pretty fast?
